A typical chemical reaction will be spontaneous if
-
enthalpy change is negative
- free energy change is greater than one
- entropy change is zero
- enthalpy and free energy change are equal
The correct answer is: A
Explanation
A reaction which is exothermic (ฮH negative) and results in an increase in the entropy of the system (ฮS positive) will always be spontaneous. Also, if ฮG is negative, the reaction will be spontaneous because the reaction can take place on it's own without any external source.
